Create a column vector.

A=(1:10)'

A =10×11 2 3 4 5 6 7 8 9 10

Useflipudto flip the elements ofAin the vertical direction.

B = flipud(A)

B =10×110 9 8 7 6 5 4 3 2 1

The order of the elements inB是相反的compared toA.

Create a 3-by-3 cell array of characters.

A = {'a''b''c';'d''e''f';'g''h''i'}

A =3x3 cell{a} {b} {' c '} {' d '}{“e”}{' f '}{‘g’}{' h '}{”i'}

Change the order of the rows in the vertical direction by usingflipud.

B = flipud(A)

B =3x3 cell{'g'} {'h'} {'i'} {'d'} {'e'} {'f'} {'a'} {'b'} {'c'}

The order of the first and third rows ofAis switched inB, while the second row remains unchanged.

Create a multidimensional array.

A = cat(3, [1 2; 3 4], [5 6; 7 8])

A = A(:,:,1) = 1 2 3 4 A(:,:,2) = 5 6 7 8

Ais an array of size 2-by-2-by-2.

Flip the elements on each page ofAin the vertical direction.

B = flipud(A)

B = B(:,:,1) = 3 4 1 2 B(:,:,2) = 7 8 5 6

The result,B, is the same size asA, but the vertical order of the elements is flipped. The operation flips the elements on each page independently.
